JOURNAL BOX.

Application filedJ'uly 21,

To all whom it ma 3 concern:

Be it known that we, EUGENE LENS. of Pointe Claire, in the Province of Quebec, Canada, and JOEL S. COFFIN, J r., of

Lisbon, in the county of Grafton and State of New Hampshire, U.- S. A., both cit zens of the United States, have invented certain new and useful Improvements in Journal Boxes, of-which the following is a specification.

This invention relates to journal-boxes for railway vehicles and is particularly useful in connection with trucks, such as the locomotive trucks, shown, described and claimed-in our copending applicatio11,.Serial No. 576,616, filed July 21, 1922.

It is one of the primary objects of our invention to provide a self-aligning journal box which will maintain itself in alignment with the axle thus avoiding running hot, excessive wear on the brasses orother bearing employed. and similar difliculties.

Another object of the invention is the provision of a box which will reduce pedes-' tal jaw wear and which is not a'fi'ected by lateral wear within wide limits.

The foregoing. together with such other objects as may hereinafter appear, or are. incident to our invention. we obtain by means of a construction which we have illustrated in preferred form in the accompanying drawings, wherein:

Fig. 1 is a fragmentary side elevation and partial section of a pedestal and box embodying our invention Fig. 2 is a sectional view through the pedestal illustrating the box inside elevation; and

Fig. 3 is a horizontal section through the pedestal illustrating the box in plan view.

On reference to'Fig. 1 it will be seen that we have illustrated a portion of a truck frame 7 having a pedestal 8 adapted to receive the journal box A between its jaws 9.

L. SoHEL- 1922. Serial No. 573,618.

The box A, ingeneral construction, may be of any preferred type. We provide the box, however, with 'a lurality of; curved bearing surfaces, where t e box bears on the pedestal parts. In the embodiment shown we employ a curvedor arcuate insert 10 in the top of the box and similarly curved insert-s 11 at the sides ofthe box, such inserts being located in the middle vertical plane of the box, the direction of curvature and clearances being such that the box, in a sense, can rock within the pedestal in an amount under all conditions-of service sufiicient to permit the box to remain in alignment with the axle 12. The mounting of the box in the pedestal is thus somewhat after thenature of a ball and socket joint and has capacity for a universal-like motion.

The practical advantages of our construction will be manifest; and it is especially useful in such constructions where there is a'liability of springing of the truck frame or where there are other conditions tending to produce disal'ignment of the boxes with the axle. Y

What we claim is:

1. In combination. a journal box for railway vehicles, a part carrying the box and pads secured to the box at the sides thereof having a-substantially vertical line contact with the carrying part.

2. In combination. a journal box for railway vehicles, a part carrying the box and pads secured to the box at the sides thereof having a substantially vertical line contact with the carrying part together with a pad secured to the top of the box having a horizontal line contact with the said part in a direction transverse the box.

In testimony whereof, we have hereunto signed our names.
